### About this course

In this course, we explore the foundations of complex analysis in one variable.
The main object of study are holomorphic functions, which are functions that are
differentiable in the complex sense. Strangely enough, if such a function can
be differentiated once, it can be differentiated infinitely many times, and in fact
admits a power series expansion (i.e. is analytic). To prove this remarkable fact,
we develop integration along contours (Cauchy's theorem). Another remarkable property
of holomorphic functions is that the value of a holomorphic function at a point z in a domain
Omega can be recovered from the values of the function on the boundary of Omega.
Further topics include:
the Schwarz lemma, the argument principle and residue calculus.

### Marking scheme (tentative)

We will have five homework assignments, worth 12% each. The final will be 40%, due the last day of classes.
